I checked out Mauna Kea, Volcano Park, and Captain Cook in Kona, and South Point. Here is a picture of Green Sands in South Point. The sand has Olivine in it (a semi-precious stone) and so it is green!
I want to stay longer because there is so much to see and do. I haven't even explored Hilo yet, or the Hamakua. I've heard amazing things about a place called Waipio Valley. I talked to Allan Yoza, who is a farm owner, and I might stay on his farm. He said it was in Puna, which I haven't been to yet. He does a work exchange program and it sounds like it will be a good way for me to stay on the island without increasing my expenses.
